It was discovered that libntlm through 1.5 relies on a fixed buffer size for tSmbNtlmAuthRequest, tSmbNtlmAuthChallenge, and tSmbNtlmAuthResponse read and write operations, as demonstrated by a stack-based buffer over-read in buildSmbNtlmAuthRequest in smbutil.c for a crafted NTLM request.
For Debian 8
Jessie, this problem has been fixed in version 1.4-3+deb8u1.
We recommend that you upgrade your libntlm packages.
